openshift-origin-server搭建并部署容器应用

准备主机、操作系统、配置操作系统、主机映射等

OpenShift平台使用的容器引擎为Docker，安装Docker软件

启动服务，并设置为开机自启动

[root@node01 ~]# systemctl start docker
[root@node01 ~]# systemctl enable docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.

运行一个DockerHub的镜像，启动一个go语言的小程序监听8080及8088端口

[root@node01 ~]# docker run -it openshift/hello-openshift
Unable to find image 'openshift/hello-openshift:latest' locally

下载openshift-origin-server-v1.5.1-7b451fc-linux-64bit.tar.gz,解压后重命名

[root@node01 app]# tar -zxvf /app/install/openshift-origin-server-v1.5.1-7b451fc-linux-64bit.tar.gz

将OpenShift相关命令加入PATH，/etc/profile中添加，也可在bash_profile中添加

[root@node01 app]# vim ~/.bash_profile

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs
export OPENSHIFT_HOME=/app/openshift
PATH=$PATH:$HOME/bin:OPENSHIFT_HOME/

export PATH

执行source使配置生效。

[root@node01 app]# source ~/.bash_profile

执行openshift version 查看当前版本，测试是否成功。

[root@node01 app]# openshift version
openshift v1.5.1+7b451fc
kubernetes v1.5.2+43a9be4
etcd 3.1.0

进入/app/openshift目录，执行openshift start命令启动OpenShift Origin。

[root@node01 openshift]# openshift start

创建helloworld项目

部署完成项目主页

此处可见已有一个在运行中的实例，查看容器实例的ip，访问helloworld项目。

[root@node01 ~]# curl 172.17.0.3:8080
Hello OpenShift!

至此第一个容器应用部署完成。
